Hey guys please help

zimovet [89]

Answer:

$7.98 \:m$

Step-by-step explanation:

Area of a triangle is base times height divided by 2.

$A= \frac{bh}{2}$

$69.6= \frac{b \times 17.45}{2}$

$69.6 \times 2= b \times 17.45$

$139.2=b \times 17.45$

$\frac{17.45b}{17.45}=\frac{139.2}{17.45}$

$b=\frac{2784}{349}$

$b=7.97707$

The appropriate unit is meters.

Ivahew [28]

Answer: D.

Step-by-step explanation: Add all of the sides' lengths together. The rest of the wall beneath where "5 ft." is measures as 6 ft. Add that to the 5 ft of the rest of the wall and you'll have 11 for the whole right wall. Add 11 to 8, 10 and 12, and you'll have 41 which is close to the last choice so you're safest bet is D.
